A five-level inverter topology for four pole induction motor drive using four two-level inverters and two isolated DC sources

Abstract: In this paper, a five-level inverter configuration is presented to improve the voltage and current harmonic profile. This topology is constructed based on the stator winding configuration of a four pole induction motor. Identical voltage profile winding coils of four pole induction motor are disconnected and fed with four two-level inverters. These four inverters are supplied with two isolated dc sources to block the path for zero sequence currents through the motor phase windings. Level shifted carrier based … Show more

“…The switching sequence for generating a voltage waveform with three levels is shown in Table I. The power of the PV array decreases considerably with partial shading [10]. The use of bypass diodes or the parallel connection of a larger number of panels is an efficient way to reduce the power reduction due to partially uneven shading [10] [19].…”

“…These problems are minimized by the use of power electronic multilevel inverters [5] - [7].Even supposing accustomed multilevel inverters have many advantages, they have certain disadvantages, such as the problem of balancing the neutral point voltage [8], the requirement for a larger statistics of capacitor banks [9]. ] and isolated DC power sources [10]. To diminish these disadvantages of typical multilevel inverters, plentiful multilevel inverter configurations have been proposed in the literature.…”

“…To address these challenges, multi-level inverters have emerged with different topologies. The traditional topologies include diode clamped, flying capacitor, and cascaded H-bridge configurations [2][3][4][5]. Among these, diode clamped and cascaded H-bridge topologies have gained prominence in various applications [6][7][8].…”

“…Moreover, if any switch of a two-level inverter fails, entire system will not function. Also, the rate of rise of output voltage (dv/dt) of this inverter is also significantly high [6]- [7]. All the aforementioned issues can be rectified by using multilevel inverters [8]- [9].…”
